The competition, run by the journal Science and the American Association for the Advancement of Science, aims to turn a graduate's work into a jargon-free interpretative dance that anyone can understand.

It also presents itself as a solution to the awkward reaction many people experience when they try to explain their PhD topic.

Peter, a self-confessed shy research associate who is "more comfortable hiding behind the computer monitor", agreed to enter the competition after pressure from his labmates.

"A turning point was my boss's enthusiastic laughter when encouraging me to do it," says Liddicoat. "And the realisation that this would tackle head-on the ominous question, 'So what is your PhD about?'"

Peter's video, 'A Super-Alloy is Born', turns his discovery of a super-strong aluminium alloy with world-record properties into a burlesque circus show. The video took six months and included the creative talents of dozens of colleagues from the Centre for Microscopy and Microanalysis and the University's Faculty of Science.

Peter is the second Australian in a row to win the international competition, and the first to win for a PhD dance based on atom microscope science.

Peter hopes to use the video to draw attention to his crowd funding project to build an atom microscope for biomedical research.
